5. Setup

5.1 Battery Installation

The ANENG A3015 requires two AAA batteries for operation. Batteries are typically not included.

1. Locate the battery compartment cover on the back of the multimeter.
2. Use a small screwdriver (if necessary) to open the battery compartment.
3. Insert two AAA batteries, ensuring correct polarity (+ and -).
4. Close the battery compartment cover securely.

5.2 Powering On/Off

• To power on: Press and hold the Power Button (labeled with a power symbol) for approximately 2 seconds.
• To power off: Press and hold the Power Button for approximately 2 seconds.
• The device features an automatic shutdown function after 15 minutes of inactivity to conserve battery life.

6. Operating Instructions

The ANENG A3015 offers various measurement modes. Use the SEL Function Toggle Key to cycle through the available functions.

6.1 AC/DC Voltage Measurement

Figure 5: Functional Measurements

1. Connect the black test lead to the COM Jack.
2. Select the appropriate AC or DC voltage measurement mode using the SEL Key. The device features auto-ranging.
3. Touch the nib probe to one point of the circuit and the black test lead to the other point.
4. Read the voltage value displayed on the LCD screen.

6.2 Resistance Measurement

1. Connect the black test lead to the COM Jack.
2. Select the Resistance measurement mode using the SEL Key.
3. Touch the nib probe and the black test lead to the two ends of the component or circuit you wish to measure.
4. Read the resistance value displayed on the LCD screen.

6.3 On-off (Continuity) Test

1. Connect the black test lead to the COM Jack.
2. Select the Continuity mode using the SEL Key.
3. Touch the nib probe and the black test lead to the two points of the circuit.
4. If the resistance is less than 50Ω, the buzzer will sound, and the backlight will turn red, indicating continuity.

6.4 Live Line Detection

Figure 6: Live Line Detection

1. Select the LIVE mode using the SEL Key.
2. Carefully touch the nib probe to the suspected live wire.
3. If a live wire is detected, the screen will display "FireWire" (or similar indicator), turn red, and emit a beeping sound.

6.5 Naught Line Detection

When in LIVE mode, touch the nib probe to the neutral (naught) line. The screen will display "LIVE" without any sirens, indicating it's not a live wire.

6.6 NCV (Non-Contact Voltage) Sensing

Figure 7: NCV Sensitivity Settings

1. Select the NCV mode using the SEL Key.
2. Bring the nib probe close to the wire or electrical outlet without making direct contact.
3. The screen will display "NCV". A green backlight indicates a weak electric field, while a flashing red backlight and beeping sound indicate a strong electric field (live voltage).
4. Press the H/LIVE Button to switch between High (HI) and Low (LO) sensitivity for NCV detection.

6.7 P Phase Sequence Detection

Figure 8: Phase Sequence Detection

1. Select the P (Phase) mode using the SEL Key.
2. Touch the nib probe to the first phase (A) of a three-phase electric system. Wait for a beep.
3. Then, touch the nib probe to the second phase (B). A beep will be issued.
4. Finally, touch the nib probe to the third phase (C). A beep will be issued.
5. The multimeter will indicate whether the phase sequence is forward or reverse.

6.8 Line Breakpoint Detection

Figure 9: Breakpoint Lookup

This function helps locate breaks in a live wire. Move the nib probe along the insulated wire. The device will indicate a strong signal where the line is unobstructed and a weak or no signal where the line is disconnected (breakpoint).

6.9 Data Hold Function

Press the HOLD Button to freeze the current measurement reading on the display. Press it again to release the hold and resume live measurements.

6.10 Backlight Control

Short press the Power Button to turn the LCD backlight on or off, improving visibility in low-light conditions.

7. User Tips

The ANENG A3015 is suitable for various applications, including automotive diagnostics. Here are some tips for optimal use:

• For NCV detection, ensure there are no other strong electromagnetic fields nearby that could interfere with readings.
• When testing continuity or resistance, ensure the circuit is de-energized to prevent damage to the multimeter.
• Always double-check your connections and selected function before taking a measurement.
• The spring pen line is designed to be stretch-resistant and durable, capable of stretching up to 180 cm for flexible use.
• When performing car inspections or line detection, the tester pen can be used in cases such as:
• Fog light does not light up
• Reversing light does not light up
• Horn does not sound
• Car does not ignite
• Air conditioner does not work
• The stereo cannot be used
• The turn signal is not on
• The headlights are not on

8. Maintenance

• Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, remove the batteries to prevent leakage. Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Probe Care: The metal probe is designed to be antioxidant and wear-resistant. Inspect it regularly for any signs of damage or wear.

9. Troubleshooting

If you encounter issues with your ANENG A3015, consider the following common troubleshooting steps:

• No Power: Check if the batteries are correctly installed and have sufficient charge. Replace them if necessary.
• Inaccurate Readings: Ensure the correct measurement function is selected. Check for loose connections or damaged test leads.
• No Continuity Beep: Verify that the circuit is indeed closed and the resistance is below 50Ω.
• NCV Not Detecting: Ensure the device is in NCV mode and try adjusting the sensitivity (HI/LO).

For persistent issues, please contact customer support.
